This is a from-scratch build (non-vendor/non-distribution) Host/Target = alpha ev6 Kernel source = 6.12.12
My last working kernel on this was a 2.6.x, it's been a while since I've had time to bring this system up to date, so I don't know when this may have started. I had a 3.0.102 in there, but I didn't test the networking while using it.
Please let me know what I can do to help out with figuring this one out.

I attempted to set the interface to 100MB/FDX with mii-tool but didn't seem to be having any luck, so I disconnected the cord, and it dropped this immediately:
